Description

[0002] As one of the important components of electronic equipment, printed circuit boards (PCBs) have high processing accuracy requirements. At present, key process processes such as through-hole processing, deep hole processing and back drilling processing of printed circuit boards are usually achieved by drilling machines. However, when the drilling machine is processing for a long time or the spindle parts are replaced, it is easy to cause deviations in the relative position of the spindle and the worktable. When the relative position of the spindle and the worktable has a large deviation, the processing yield of the drilling machine will be reduced. Therefore, after the drilling machine has been working for a period of time or the spindle parts of the drilling machine have been replaced, the relative position of the spindle and the worktable of the drilling machine needs to be detected.

[0003] At present, it is usually detected by manual inspection whether there is a large deviation in the relative position of the spindle and the worktable, for example, manual measurement is performed by tools such as micrometers and standard circle PINs.

[0027] In order to fully understand the present invention, detailed structures and steps will be presented in the following description to illustrate the technical solutions proposed by the present invention. The preferred embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other implementations.

[0028] The present invention discloses a spindle deviation detection method, controller, medium, program product and circuit board processing equipment. When a preset condition is met, the spindle is controlled to grab the spindle tool and enter the detection area of ​​the tool detector for mobile detection to obtain the deviation detection data of the spindle, and it is judged whether the detection deviation data of the deviation detection data and the reference detection data exceeds the preset first deviation threshold. If the detection deviation data exceeds the first deviation threshold, the spindle is compensated according to the detection deviation data. It can be seen that the present invention uses the tool detector to detect the spindle tool to obtain data as the deviation detection data of the spindle, and then realizes the deviation detection of the spindle according to the comparison of the deviation detection data and the reference detection data, and when the detection deviation data of the deviation detection data and the reference detection data exceeds the preset first deviation threshold, the spindle is compensated according to the detection deviation data. Compared with the manual deviation detection of the spindle, the purpose of improving the deviation detection efficiency is achieved. The following is an explanation through specific embodiments.

[0029] like Figure 1 FIG. 1 is a flowchart of a spindle deviation detection method disclosed in an embodiment of the present invention. The method is applicable to processing equipment with a movable spindle and a worktable, such as a drilling machine, a guillotine cutter, etc. The spindle deviation detection method in this embodiment specifically includes the following steps: S101: When a preset condition is met, the spindle is controlled to grab the spindle tool and enter the detection area of ​​the tool detector for movement detection to obtain the deviation detection data of the spindle.

[0030] It should be understood that after the circuit board processing equipment has been working for a certain period of time, errors will inevitably occur in the spindle and the worktable, resulting in reduced processing accuracy of the circuit board processing equipment. For example, the replacement of spindle parts of the circuit board processing equipment, the expansion and contraction of the spindle, and the aging of spindle parts may reduce the processing accuracy of the circuit board processing equipment. Therefore, the preset detection conditions in this embodiment may be as follows: The first detection condition is that after the circuit board processing equipment reaches a preset first time length, the spindle is controlled to grab the spindle tool and enter the detection area of ​​the tool detector for detection to obtain the deviation detection data of the spindle tool, so as to detect whether the spindle of the circuit board processing equipment is aged or expanded and shrunk due to long-term work, resulting in reduced processing accuracy of the circuit board processing equipment.

[0031] The second detection condition is to replace the spindle parts of the circuit board processing equipment, control the spindle to grab the spindle tool and enter the detection area of ​​the tool detector for detection, and obtain the deviation detection data of the spindle tool, so as to detect the spindle of the circuit board processing equipment. After the parts are updated, the spindle becomes tilted, resulting in a decrease in the processing accuracy of the circuit board processing equipment.

[0032] S102: Determine whether the detection deviation data between the deviation detection data and the reference detection data exceeds a preset first deviation threshold.

[0033] The reference detection data may be detection data set manually as needed, or the reference detection data may be detection data obtained by controlling the spindle to grab the spindle tool and enter the detection area of ​​the tool detector for detection after the circuit board processing equipment is debugged and qualified and the circuit board processing equipment enters the best working state. When the deviation detection data is equal to the reference detection data, or when the deviation detection data is very close to the reference detection data, the processing accuracy of the circuit board processing equipment can be guaranteed. Therefore, in this embodiment, the position deviation between the spindle and the workbench is detected by judging whether the detection deviation data of the deviation detection data and the reference detection data exceeds the preset first deviation threshold.

[0034] When the detection deviation data of the deviation detection data and the benchmark detection data exceeds the preset first deviation threshold, the spindle is compensated according to the detection deviation data; when the detection deviation data of the deviation detection data and the benchmark detection data does not exceed the preset first deviation threshold, the process ends until the circuit board processing equipment reaches the preset detection condition next time, and the spindle is controlled again to grab the spindle tool and enter the detection area of ​​the tool detector for detection to obtain the deviation detection data of the spindle tool, and then, it is judged again whether the detection deviation data of the deviation detection data and the benchmark detection data exceeds the preset first deviation threshold.

[0035] It should be noted that when the detection deviation data of the deviation detection data and the benchmark detection data does not exceed the preset first deviation threshold, the time for the next detection of the circuit board processing equipment can be shortened. For example, after the circuit board processing equipment has worked for a first period of time, the circuit board processing equipment is detected once to obtain deviation detection data. If the detection deviation data of the deviation detection data and the benchmark detection data does not exceed the preset first deviation threshold, the circuit board processing equipment is detected again after the circuit board processing equipment has worked for a second period of time to obtain new deviation detection data, wherein the second period of time is less than the first period of time, such as the first period of time is 30 days, the second period of time is 20 days, and so on. The third period of time is 10 days. Therefore, by gradually increasing the detection frequency of the circuit board processing equipment, it is beneficial to timely discover the deviation problems of the circuit board processing equipment.

[0036] S103: If the detected deviation data exceeds a first deviation threshold, a compensation process is performed on the spindle according to the detected deviation data.

[0037] In a specific implementation, in this embodiment, the detection deviation data can be sent to the control module of the circuit board processing equipment, so that the control module performs compensation processing on the spindle according to the detection deviation data. The control module can be a host computer of the circuit board processing equipment, and the host computer is used to control the circuit board processing equipment to perform the entire process of circuit board processing.

[0038] In summary, the present invention discloses a spindle deviation detection method, which controls the spindle to grab the spindle tool and enter the detection area of ​​the tool detector for mobile detection under the condition of meeting the preset conditions, obtains the deviation detection data of the spindle, and judges whether the detection deviation data of the deviation detection data and the reference detection data exceeds the preset first deviation threshold value. If the detection deviation data exceeds the first deviation threshold value, the spindle is compensated according to the detection deviation data. It can be seen that the present invention uses the data obtained by the tool detector to detect the spindle tool as the deviation detection data of the spindle, and then realizes the deviation detection of the spindle according to the comparison of the deviation detection data and the reference detection data, and when the detection deviation data of the deviation detection data and the reference detection data exceeds the preset first deviation threshold value, the spindle is compensated according to the detection deviation data. Compared with the manual deviation detection of the spindle, the purpose of improving the deviation detection efficiency is achieved.

[0039] In one embodiment, the deviation detection data in this embodiment includes first detection data and second detection data; wherein the first detection data is obtained by detecting that the spindle grabs the spindle tool and moves along the first direction in the detection area; The second detection data is obtained by detecting that the spindle grabs the spindle tool and moves along the second direction within the detection area, and the first direction and the second direction are different directions.

[0040] In one embodiment, the tool detector in this embodiment includes a detection area, which controls the spindle to grab the spindle tool and perform movement detection along a first direction within the detection area to obtain first detection data; and controls the spindle to grab the spindle tool and perform movement detection along a second direction within the detection area to obtain second detection data.

[0041] In one embodiment, the tool detector in this embodiment includes a first detection area in a first direction and a second detection area in a second direction. The spindle is controlled to grab the spindle tool and enter the first detection area along the first direction for mobile detection to obtain first detection data; the spindle is controlled to grab the spindle tool and enter the second detection area along the second direction for mobile detection to obtain second detection data.

[0042] In one embodiment, the tool detector in this embodiment includes a first detector and a second detector, and the first detector includes a detection area in a first direction. On this basis, step S101 can be implemented in the following manner: S201: Control the spindle to grab the spindle tool and enter the detection area of ​​the first detector along the first direction for movement detection to obtain first detection data.

[0043] S202: Control the spindle to grab the spindle tool and move along the second direction into the detection area of ​​the second detector for movement detection to obtain second detection data.

[0044] The first detector is a tool detector with the entrance of the detection area in the first direction, and the second detector is a tool detector with the entrance of the detection area in the second direction, that is, the installation positions and installation directions of the first detector and the second detector are different. Figure 3 As shown, it is a schematic diagram of the installation of the first detector and the second detector in an embodiment of the present invention, wherein 4a is the first detector, 4b is the second detector, 1 is the spindle, 3 is the workbench, 5 is the spindle tool, the first detector 4a and the second detector 4b are respectively arranged on the workbench 3, and the spindle tool 5 is clamped and fixed on the spindle 1.

[0045] In one embodiment, Figure 4 As shown, it is a schematic diagram of the deviation detection of the spindle in the first direction and the deviation detection in the second direction in this embodiment, wherein sub-figures a1 and a2 are schematic diagrams of the spindle grabbing the spindle tool for movement detection along the first direction, and sub-figures b1 and b2 are schematic diagrams of the spindle grabbing the spindle tool for movement detection along the second direction.

[0046] Specifically, the circuit board processing equipment in this embodiment is provided with a first direction motor and a second direction motor for controlling the movement of the spindle, wherein the first direction may refer to the front-back direction of the spindle, and the second direction may refer to the left-right direction of the spindle, and the specific orientations of the first direction and the second direction are not limited in this embodiment. The first direction motor is used to control the spindle to move along the first direction so as to enter the detection area of ​​the first detector for detection, thereby obtaining first detection data of the spindle tool; the second direction motor is used to control the spindle to move along the second direction so as to enter the detection area of ​​the second detector for detection, thereby obtaining second detection data of the spindle tool.

[0047] In summary, in this embodiment, by performing deviation detection on the spindle in two directions, compared with performing deviation detection on the spindle in the first direction, it is beneficial to improve the accuracy of spindle deviation detection.

[0048] based on Figure 1 In the specific implementation, step S102 in this embodiment can be implemented as follows: Figure 5 As shown: S501: Determine whether a first deviation data between the first detection data and the reference detection data exceeds a first deviation threshold.

[0049] S502: If the first deviation data exceeds a first deviation threshold, a compensation process is performed on the spindle according to the first deviation data.

[0050] In a specific implementation, when the first deviation data between the first detection data and the reference detection data exceeds a preset first deviation threshold, the spindle is compensated according to the first deviation data; when the first deviation data between the first detection data and the reference detection data does not exceed the preset first deviation threshold, the process ends until the circuit board processing equipment reaches the preset detection condition next time, and then the spindle is controlled again to grab the spindle tool and enter the detection area of ​​the tool detector for detection to obtain the first detection data of the spindle tool, and then, it is determined again whether the first deviation data between the first detection data and the reference detection data exceeds the preset first deviation threshold, and so on.

[0051] S503: Determine whether the second deviation data between the second detection data and the reference detection data exceeds a second deviation threshold.

[0052] S504: If the second deviation data exceeds the second deviation threshold, compensation processing is performed on the spindle according to the second deviation data.

[0053] In a specific implementation, when the second deviation data between the second detection data and the benchmark detection data exceeds the preset first deviation threshold, the spindle is compensated according to the second deviation data; when the second deviation data between the second detection data and the benchmark detection data does not exceed the preset first deviation threshold, the process ends until the circuit board processing equipment reaches the preset detection condition next time, and then the spindle is controlled again to grab the spindle tool and enter the detection area of ​​the tool detector for detection to obtain the second detection data of the spindle tool, and then, it is determined again whether the second deviation data between the second detection data and the benchmark detection data exceeds the preset first deviation threshold, and so on.

[0054] In summary, in this embodiment, by detecting the deviation of the spindle in two directions and performing compensation processing on the spindle in the two directions respectively, it is beneficial to improve the compensation accuracy of the spindle.

[0055] In one embodiment, the benchmark detection data in this embodiment includes first benchmark data and second benchmark data. On this basis, step S102 in this embodiment can also be implemented in the following manner: Figure 6 As shown: S601: Determine whether first deviation data between first detection data and first reference data exceeds a first deviation threshold.

[0056] S602: If the first deviation data exceeds a first deviation threshold, a compensation process is performed on the spindle according to the first deviation data.

[0057] The first reference value and the second reference value may be the same or different.

[0058] In a specific implementation, when the first deviation data between the first detection data and the first reference data exceeds a preset first deviation threshold, the spindle is compensated according to the first deviation data; when the first deviation data between the first detection data and the first reference data does not exceed the preset first deviation threshold, the process ends until the circuit board processing equipment meets the preset detection conditions next time, and then the spindle is controlled again to grab the spindle tool and enter the detection area of ​​the tool detector for detection to obtain the first detection data of the spindle tool, and then, it is determined again whether the first deviation data between the first detection data and the first reference data exceeds the preset first deviation threshold, and so on.

[0059] S603: Determine whether the second deviation data between the second detection data and the second reference data exceeds the first deviation threshold.

[0060] S604: If the second deviation data exceeds the first deviation threshold, compensation processing is performed on the spindle according to the second deviation data.

[0061] In a specific implementation, when the second deviation data between the second detection data and the second reference data exceeds the preset first deviation threshold, the spindle is compensated according to the detection deviation data; when the detection deviation data of the second deviation data and the second reference data does not exceed the preset first deviation threshold, the process ends until the circuit board processing equipment reaches the preset detection condition next time, and the spindle is controlled again to grab the spindle tool and enter the detection area of ​​the tool detector for detection to obtain the second deviation data of the spindle tool, and then, it is judged again whether the detection deviation data of the second deviation data and the second reference data exceeds the preset first deviation threshold.

[0062] In summary, in this embodiment, by setting corresponding reference values ​​in two directions respectively, different deviation detection standards can be implemented in the two directions respectively, which is conducive to improving the rationality of spindle deviation detection.

[0063] based on Figure 1 In the specific implementation, step S103 in this embodiment can be implemented by the following steps: Figure 7 As shown: S701: Determine whether the detection deviation data exceeds a first deviation threshold and is less than a second deviation threshold.

[0064] The second deviation threshold is greater than the first deviation threshold.

[0065] S702: If the detected deviation data exceeds the first deviation threshold and is less than the second deviation threshold, compensation processing is performed on the spindle according to the detected deviation data.

[0066] S703: If the detected deviation data exceeds a second deviation threshold, the circuit board processing equipment is controlled to perform alarm processing.

[0067] If the first deviation data exceeds the first deviation threshold and is less than the second deviation threshold, the spindle is compensated according to the first deviation data; if the first deviation data is less than the first deviation threshold, the process ends; if the first deviation data exceeds the second deviation threshold, the circuit board processing equipment is controlled to perform alarm processing.

[0068] Further, when the detected deviation data includes the first deviation data detected in the first direction and the first deviation data detected in the second direction, if both the first deviation data and the second deviation data exceed the first deviation threshold and are less than the second deviation threshold, the spindle is compensated in the first direction according to the first deviation data, and the spindle is compensated in the second direction according to the second deviation data. If any one of the first deviation data and the second deviation data exceeds the second deviation threshold, or both the first deviation data and the second deviation data exceed the second deviation threshold, the circuit board processing equipment is controlled to perform an alarm process.

[0069] In one embodiment, the alarm processing in this embodiment includes but is not limited to voice alarm reminders, text alarm reminders, and SMS reminders of circuit board processing equipment.

[0070] Firstly, the voice alarm reminder in this embodiment can be realized by controlling the voice equipment (such as buzzer, speaker, etc.) of the circuit board processing equipment through the control system of the circuit board processing equipment.

[0071] Secondly, the text alarm reminder in this embodiment can be realized by controlling the display device (such as the central control display screen, etc.) of the circuit board processing equipment through the control system of the circuit board processing equipment.

[0072] Thirdly, the SMS reminder in this embodiment can send alarm data to the background server through the control system of the circuit board processing equipment, so that the background server sends the alarm data to the communication terminal of the person in charge of the circuit board processing equipment, such as a mobile phone.

[0073] The alarm processing is used to indicate that the spindle of the circuit board processing equipment needs to be re-debugged. It should be understood that when the first deviation data and / or the second deviation data is greater than the second deviation threshold, it indicates that the spindle of the circuit board processing equipment has a large degree of deviation. If the spindle is not debugged, the yield rate of the circuit board processing equipment will be reduced.

[0074] In one embodiment, the compensation processing in this embodiment includes: compensating the coordinates of the spindle center point in the machine coordinate system of the circuit board processing equipment according to the detection deviation data, or adjusting the coordinates of the worktable in the machine coordinate system of the circuit board processing equipment according to the detection deviation data to achieve compensation for the spindle center point.

[0075] based on Figure 1 In the specific implementation, an air clamp is provided on the workbench in this embodiment, and the air clamp is used to fix the circuit board placed on the workbench. On this basis, after step S103, the following steps are also included, such as Figure 8 As shown: S104: Control the spindle to grab the spindle tool to process the circuit board.

[0076] It should be understood that after the spindle is compensated, the processing accuracy of the spindle has been improved. Therefore, by controlling the spindle to grab the spindle tool to process the circuit board, a circuit board with higher accuracy can be obtained.

[0077] Among them, controlling the spindle to grab the spindle tool to process the circuit board includes but is not limited to drilling, milling, breakpoint processing, etc. In this embodiment, after the spindle is compensated, the type of processing of the circuit board by the spindle is not limited.

[0078] based on Figure 1 In the specific implementation, the tool detector includes a receiver and a transmitter, the transmitter is used to emit a detection beam, and the receiver is used to receive the detection beam emitted by the transmitter. On this basis, step S101 in this embodiment can be implemented by the following steps: Fig. 9 As shown: S901: When the spindle tool contacts the detection light beam in the detection area, the first position data of the spindle tool is recorded.

[0079] S902: When the spindle tool is controlled to leave the detection light beam, the second position data of the spindle tool is recorded.

[0080] By controlling the spindle to grab the spindle tool and enter the detection area of ​​the tool detector, when the spindle tool contacts the detection beam in the detection area, the detection beam is blocked by the spindle tool, and the receiver cannot receive the detection beam emitted by the transmitter. At this time, the first position data of the spindle tool is recorded. At the same time, after controlling the spindle tool to contact the detection beam, the spindle tool continues to be controlled to move. When the spindle tool leaves the detection beam, the detection beam is no longer blocked by the spindle tool, and the receiver can normally receive the detection beam emitted by the transmitter. At this time, the second position data of the spindle tool is recorded.

[0081] In one embodiment, Fig.10, which is a schematic diagram of the structure of the tool detector in this embodiment, wherein 1 is the spindle, 5 is the spindle tool, 6 is the transmitter, 7 is the receiver, and 8 is the detection beam. The spindle tool 5 is clamped and fixed on the spindle 1, the transmitter 6 and the receiver 7 are arranged oppositely, and the transmitter 6 transmits the detection beam 8 to the receiver 7.

[0082] In a specific implementation, in this embodiment, the first position data and the second position data of the spindle tool can be read through the grating ruler displacement sensor. When the tool detector is in a normal state, that is, the transmitter can normally emit a detection beam, and the receiver can normally receive the detection beam emitted by the transmitter, the tool detector can continuously send a high-level signal. When the spindle tool just contacts the detection beam, due to the obstruction of the spindle tool, the receiver cannot normally receive the detection beam emitted by the transmitter. At this time, the tool detector can send a low-level signal, and then when receiving the low-level signal, the first position data of the spindle tool is read through the grating ruler displacement sensor. When the spindle tool leaves the detection beam, the receiver can normally receive the detection beam emitted by the transmitter. At this time, the tool detector can send a high-level signal, and then when receiving the high-level signal, the second position data of the spindle tool is read through the grating ruler displacement sensor. Based on this, the acquisition of the first position data and the second position data can be achieved.

[0083] S903: Calculate deviation detection data according to the first position data and the second position data.

[0084] In a specific implementation, the first position data can be recorded as 0, and the second position data can be recorded as the displacement distance relative to the first position data, that is, the displacement distance from the first position data to the second position data is recorded by the grating ruler displacement sensor. Alternatively, the first position data and the second position data are both the displacement distances of the spindle tool in the same displacement direction. On this basis, the deviation detection data can be obtained by subtracting the first position data from the second position data, or the deviation detection data can be obtained by subtracting the first position data from the second position data and calculating the average value. That is, the displacement distance recorded by the second position data is subtracted from the displacement distance recorded by the first position data, and then divided by 2 to obtain the deviation detection data.

[0085] In summary, in this embodiment, the deviation detection data is obtained by detecting the displacement distance required for the spindle tool to pass through the detection beam, that is, the first position data and the second position data. Compared with manual measurement, the purpose of improving the spindle tool detection efficiency can be achieved.
